Hempafire Optima 500, developed by Hempel, is an advanced fire-resistant paint engineered to effectively prevent the spread of flames for up to 3 hours. With its matte white appearance, it not only provides superior fire protection but also enhances the aesthetic appeal of steel surfaces. Specifically designed as an intumescent coating for structural steel, it serves as a reliable defense against cellulosic fires. One of its notable features is its ability to maintain weather resistance for up to 12 months without requiring an additional coat of paint. However, ensuring thorough drying and protection from moisture-related factors such as condensation, running water, or pooling water is essential to preserve its effectiveness over time.
